C-Z Purlins
1. Saving in steel up to 40%
2. Saving in construction cost up to 30%
3. Light weight reduces handling and transportation cost.
4. Saving in construction time.
5. Close tolerances on sectional dimensions due to process of cold roll forming.
6. Economy due to reduction in dead weight on the main frame structure.
7. Ability to span long lengths.
8. Fast to erect and easy handling.
9. Assured dimensions and straightness.
10. No site drilling/cutting required.
11. Tailor made section lengths lead to no wastage and speedy erection.
12. Also available in G.I.
